Hey Tim

Well I just got the email.
Ralph will run the Partner saw motor tomorrow to do some testing and recommend a prop.
Any guesses on the prop size and RPM? He tests all of his engines with out mufflers.
My G-62 turns a 22x10w APC pretty good and this engine is about 15% bigger.

The Piston on the Echo twin had a "couple of scratches in it and the cylinder is okay".
It should ship soon also but at least I can finnish the 540 now.
